3Rivers Internal FOC Weight Jig

Add Front of Center weight to your wood arrows with the 3Rivers Internal FOC Weight Jig. Designed to make it incredibly fast and simple to drill your arrows to bump up your point weight or nock end weight.

This Internal FOC Weight Jig is designed to allow you to precisely drill internal cavities in the point end or nock end of your 23/64" and 11/32" wood arrow shafts. The set includes the jig as well as a 9/64" wide by 3" long drill bit. We offer a 6" long drill bit for added drilling depth.

Simply insert the wood arrow shaft, then use a variable speed hand drill (not included) to drill holes in the point or nock end of your shaft. Then insert a weighted rod into the cavity. We recommend using a 1/8" wide rod. See our weighted rods here.

The slots are marked 23/64 and 11/32 for convenient identification. The wood arrow shaft slides in 2" for a secure hold to allow for precision drilling down the middle of the arrow.
